Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a flush toilet chemical supply device installed in a supply tray of a water storage tank in a water storage tank type flush toilet.

  Conventionally, this type of drug supply device has a lid that is detachably provided above the supply device main body so that a drug can be accommodated therein, and the cover has a volatilization port for diffusing volatile fragrance of the drug. And an intake for taking in water are formed. Further, a pedestal for mounting a solid medicine is formed inside the supply tool main body, and a drain port for discharging water flowing from the water intake port or the volatilization port is formed at the center of the pedestal. . In addition, a plurality of substantially fan-shaped water intake ports are formed radially on the base of the supply tool main body. The water that has fallen from the faucet of the water supply pipe to the supply pan side of the water storage tank flows into the water storage tank through the flow hole of the supply pan, and a part of the water is taken out of the intake port of the lid of the drug supply device and the pedestal. It flows into the inside of the supply device main body from the mouth and the volatilization opening of the lid, and comes into contact with the medicine, thereby dissolving the medicine, and the dissolved medicine flows through the drain port together with the inflowing water from the drain hole of the water storage tank to the tank. So that it flows into the inside.

  However, in the above-mentioned conventional drug supply device, since water flows into the inside of the supply device body from the water intake port of the lid, the water intake port of the pedestal, the volatilization port of the lid, etc., and comes into contact with the drug, the solid material is solid. In some cases, the dissolution rate of the drug was increased, and the drug consumption was increased.

  In order to solve this, Patent Literature 1 discloses a technique of dissolving an appropriate amount of a drug by separately containing two types of a solid drug for cleaning and a drug for aroma. With such a configuration, when purchasing or refilling a drug, the assembly work is complicated and troublesome for the user, and the production cost is high because two types of the drug, a detergent and a fragrance, are required. is there.

Therefore, an object of the present invention is to provide a medicine supply device which does not require two kinds of medicines and can ensure stable dissolution and fragrance of the medicines by placing a single medicine in a storage section. .
JP-A-10-252119 (paragraphs 0012 to 0018, FIG. 1)

  In order to achieve the above object, the present invention is a medicine supply device placed on the upper surface of a water supply tray of a flush toilet storage tank, wherein the medicine supply device includes a lid and a supply device main body, The supply device main body is provided with a storage section for storing the medicine, a water intake port for taking in water for bringing the medicine into contact with the storage section, and a drain port for draining water that has entered the water intake port and contacted the medicine, Further, in the drug supply device provided with a volatilization port for diffusing the volatile fragrance contained in the drug into the drug supply device and a surplus water discharge port for discharging surplus water from the volatilization port, the volatilization port or A water-blocking hand throw is provided to prevent water entering from a surplus water discharge port from entering the storage section, and the volatilization port and the surplus water discharge port are arranged outside the water-blocking hand throw. I do.

  According to the above configuration, a water impeding hand is formed to prevent water flowing from the volatilization port and the surplus discharge port from entering the storage section for storing the medicine. Even if it flows into the supply device through the outlet, it does not come into contact with the medicine in the storage part, and is limited to water from the water intake formed in the storage part, so that an appropriate amount of medicine can be dissolved It becomes.

  Examples of the water-impeding hand throw include a mode constituted by a water-blocking wall formed around the accommodation section and a mode constituted by a water-blocking piece formed on the side of the medicine accommodating section of the volatilization opening. In the case of a water impervious wall, by arranging the volatilization port and the surplus discharge port outside the impermeable wall of the storage unit, water dropped from the faucet passes through the volatilization port and the surplus discharge port to the inside of the supply tool main body. Even if it flows in, it does not come into contact with the medicine, but only comes in contact with the medicine surrounded by the impermeable wall. It becomes possible.

  The shape and arrangement of the impermeable wall are not particularly limited as long as the water can be prevented from coming into contact with the medicine at least from the volatilization port and the surplus discharge port. For example, the impermeable wall can be a cylindrical wall or a raised wall. In the case of a cylindrical wall or a raised wall, one end of the wall is open, so that the medicine can be easily stored in the storage section surrounded by the impermeable wall from one end.

  In addition, the height of the impermeable wall may be any height as long as the water splashing from the outer peripheral side is prevented from splashing on the inner medicine, and on the other hand, a space where the fragrance volatilized from the medicine is smoothly guided to the volatilization opening side. It is preferable that the height is such that can be secured above.

  For example, when the impermeable wall is erected from the supply device main body, it is preferable that the minimum height is 1.5 cm or more from the water supply tray of the water storage tank on which the medicine supply device is mounted. In addition, it is possible to prevent the chemical from contacting at least the water accumulated at the bottom side of the supply tool main body (such as water flowing from a surplus water discharge port to be described later or water dropped along the inner surface of the main body from the volatilization port).

  The height of the impermeable wall is more preferably set to be substantially the same as the height of the medicine, so that the water comes into the inside of the main body from the volatilization opening and jumps up from the bottom of the main body and comes into contact with the medicine. Can be prevented. Furthermore, the height of the impermeable wall can be increased to the level of the volatilization opening. This can prevent contact with the water scattered directly from the volatilization port to the medicine side.

  Further, the impermeable wall can adopt either of the form integrally formed on the supply tool main body or the form formed separately, but the production cost is reduced by integrally forming with the supply tool main body. be able to. Further, as a medicine supply device, there is a medicine supply device having a lid detachably mounted above the supply device main body in addition to the container-like supply device main body. In, the impermeable wall may be formed on the lid side. When a water impervious wall is formed on the lid, the volatilization port is generally formed on the lid, so the volatilization port is formed outside the water impervious wall, and the water flowing from the volatilization port becomes Avoid contact. However, since it is necessary to guide the fragrance volatilized from the drug to the volatilization port outside the impermeable wall, a passage between the drug container and the volatilization port is provided to the extent that the water flowing from the volatilization port does not come into contact with the drug. Form.

  In addition, in principle, a surplus water discharge port for discharging surplus water that has flowed in from the volatilization port outside the impermeable wall of the storage unit must be formed. The volatilization opening may be formed inside the impermeable wall. In such a case, a water-blocking piece will be provided to guide the water flowing from the volatilization opening to the outside of the water-blocking wall. This makes it possible to smoothly discharge the water flowing from the volatilization port to the outside from the surplus water discharge port. In addition, in order to prevent the water that has flowed in from the intake port from accumulating inside the impermeable wall more than necessary, a water introduction hole that guides a part of the water that has flowed in from the intake port to the surplus water discharge port side is formed in the impermeable wall. It can also be formed. Thereby, the amount of water taken in from the water intake provided inside the impermeable wall can be adjusted. This water introduction hole can be set in various shapes such as a slit shape and a plurality of round holes, but has a hole area that can prevent at least water dropped from the volatilization port from excessively flowing into the medicine side. Is preferred.

  In addition, in the aspect in which the water-blocking piece as the water-blocking hand is formed on the medicine container side of the volatilization port as described above, the water flowing from the volatilization port does not directly contact the medicine, so There is an advantage that there is no need to arrange a volatilization port, and the positional relationship with the medicine container is not particularly limited.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a water storage tank for a flush toilet in which a drug supply device according to the present invention can be installed, FIG. 2 is an exploded perspective view of the drug supply device in the present embodiment, FIG. 3 is a plan view of a supply device body, and FIG. Is a bottom view of the supply device main body, and FIG. 5 is an overall sectional view of the medicine supply device.

  As shown in FIG. 1, the drug supply device according to the present invention is placed on a water supply tray 2 of a water storage tank 1 of a flush toilet so that a part of water falling from a faucet 3 above the water supply device can pass therethrough. It is a container.

  As shown in FIG. 2, this container-like drug supply device is composed of a lower supply device main body 5 and an upper lid 7 detachably attached to the main body. It can be accommodated. The supply device body 5 has a bowl shape with an open upper surface, and a convex portion 6 formed on the outer periphery of the upper end thereof is pulled by a rib 8 formed on the inner periphery of the lower end of an inverted bowl-shaped lid 7. By hanging, the lid 7 is detachably attached to the supply tool main body 5.

  As described above, the supply tool main body 5 has a bowl shape with an open upper surface, and has a drain port 14 formed in the center thereof. The legs 16 are formed at intervals and can be fitted into the sink holes of the tray 2. Further, a projection 20 is formed on the outside of the bottom of the bowl of the main body 5 so as to protrude downward on the outside of the leg 16 and comes into contact with the pan 2. The projection 20 allows water falling from the faucet 3 to fall between the main body 5 and the pan 2. Can be caused to flow into the sink hole of the tray 2.

  Further, inside the supply device main body 5, a storage portion 23 for storing the medicine 9 is formed at a central portion thereof. The accommodating portion 23 is formed at the center of the inner bottom surface of the supply device main body 5, and has a pedestal portion 12 on which the medicine 9 is placed, and a cylindrical water-impervious wall 11 erected around the pedestal portion 12. A space surrounded by is formed so that the medicine 9 can be inserted into the storage portion 23 from the upper end opening of the cylindrical water-impervious wall 11.

  The pedestal portion 12 is composed of a plurality of radially divided bodies protruding from the bottom of the bowl of the main body 5 with the center of the drain port 14 as a center, and the upper surface thereof is formed in a planar shape. And between the divided bodies, there is a valley formed lower than that, and the bottom surface thereof is an inclined surface 15 which is inclined downward to the drain port 14 in the center of the main body, and the water inside the impermeable wall 11 is The passage leads to the drain port 14.

  A plurality of water inlets 13 for taking in a part of the water accumulated in the tray 2 into the supply tool main body 5 are provided radially outside of the divided body constituting the pedestal portion 12 and inside the impermeable wall 11. Is formed. The water intake 13 is formed in a slit shape that opens on the outer surface side of the bottom of the main body. The water intake 13 restricts too much water from flowing into the supply tool main body 5, but the shape is not limited to the slit shape, but may be another hole shape, for example, a small round hole shape. And so on.

  Further, a plurality of surplus water discharge ports 14a for draining water flowing from the volatilization port 10 and the like are formed in the outer periphery of the water-impervious wall 11 in the radial direction and at the bottom of the bowl of the supply tool body 5, and are mainly provided with a lid. Water falling from the volatilization opening 10 formed in the body 7 can be discharged.

  The water impervious wall 11 functions as a water impervious means for preventing water flowing from the volatilization port 10 from entering the storage part 23, and as shown in FIG. The height is set to be substantially the same as the height of the new medicine 9, and water that falls from the volatilization opening 10 and hits the bottom of the main body and rebounds can be prevented from splashing on the medicine 9. . The height of the water-impervious wall 11 is set to be substantially the same as the upper edge of the supply tool main body 5, so that the main body is not bulky when the main body is packed or transported.

  Further, the inner diameter of the impermeable wall 11 is set to be substantially the same as or slightly larger than the outer diameter of the medicine 9, thereby enabling the positioning of the medicine 9 placed on the pedestal portion 12. I have. A plurality of slit-shaped water guide holes 17 are formed in the water-blocking wall 11 at intervals above substantially the middle in the height direction. The drainage can be adjusted so that the medicine 9 in 11 does not flood. The position of the water introduction hole 17 is not limited to this, and the height position of the slit may be appropriately selected so that the dissolution of the medicine 9 becomes an appropriate amount. Further, the shape of the water guide hole 17 is not limited to the slit shape.

  As shown in FIG. 2, the lid 7 is formed in an inverted bowl shape, and a plurality of volatilization ports 10 for diffusing volatile fragrance from the medicine 9 to the outside are formed on the outer periphery thereof. The volatilization port 10 is formed so as to be located radially outside of the impermeable wall 11, and is regulated so that water flowing from the volatilization port 10 into the supply device main body 5 does not directly hit the medicine 9. In addition, the shape of the lid 7 is not particularly limited, and various shapes such as a flat plate shape and a hat shape can be adopted in addition to the above-mentioned inverted bowl shape.

  The medicine 9 is a mixture of a surfactant exhibiting a cleaning effect and a fragrance component for emitting a scent. In the present embodiment, a medicine having a truncated cone-shaped solid form is used. I have. The drug 9 is prepared by tableting or kneading the above-mentioned raw materials, and is excellent in washing effect and fragrance, but is not limited thereto. For example, other components, for example, a deodorant may be mixed with the fragrance, or a deodorant may be mixed instead of the fragrance. In addition to the truncated cone as in the present embodiment, various forms of the solid form such as a truncated pyramid, a pyramid, a cylinder, and a prism can be used as the form of the medicine 9.

  The medicine supply device configured as described above contains the medicine 9 and is used by inserting and mounting the legs 16 of the supply device main body 5 into the sink holes of the receiving tray 2 of the water storage tank 1. When water falls from the faucet 3, the water is supplied from the receiving tray 2 through the bottom of the bowl of the supply tool body 5 into the water storage tank 1 through the flow hole. Part of the water that has fallen into the tray 2 penetrates into the pedestal portion 12 of the supply tool main body 5 from a water intake port 13 formed at the bottom of the bowl of the supply tool body 5, and comes into contact with the medicine 9 on the pedestal portion 12, and 9 is dissolved in an appropriate amount. The dissolved drug 9 mixes with water, flows through the inclined surface 15 between the pedestals 12, and flows into the drain hole from the central drainage port 14.

  On the other hand, a part of the water that has fallen from the faucet 3 directly hits the lid 7 of the medicine supply device and flows into the supply device main body 5 from the volatilization port 10, but the inflow water is blocked by the impermeable wall 11. As a result, it flows out of the surplus water discharge port 14a outside the impermeable wall 11 with almost no contact with the medicine 9. As described above, the contact with the medicine 9 surrounded by the impermeable wall 11 is limited to the water from the water intake 13 formed inside the storage portion 23, and the dissolution of the medicine 9 Can be suppressed as compared with the conventional case, and an appropriate amount of the drug 9 can be dissolved.

Further, when a large amount of water flows into the supply device main body 5 from the water intake port 13, particularly when a large amount of water is accumulated in the tray 2, a large amount of water also flows into the supply device main body 5. At this time, a part of the water that has flowed in from the water intake 13 is discharged to the outside from the water introduction hole 17 formed in the impermeable wall 11 through the outer surplus water discharge port 14a. Thus, the amount of water taken in from the water intake 13 inside the impermeable wall 11 can be adjusted. With such dissolution of the chemical 9, the fragrance volatilized from the chemical 9 is blocked from the space above the impermeable wall 11. Since the heat is radiated to the outside through the volatilization opening 10 of the lid 7 outside the water wall 11, the sanitary space can be made comfortable.

  FIGS. 6 to 8 show a comparison of the residual ratio of the chemical 9 under various test conditions between the example in which the impermeable wall 11 of the present embodiment is provided and the comparative example without the impermeable wall 11. In the test condition 1 shown in FIG. 6 (a), the medicine 9 is housed in the housing part of the supply tool main body 5, attached to the receiving tray 2 of a low tank (TOTO S721B manufactured by Totoki Kiki Co., Ltd.) of a household toilet, and the low tank flows in. The temperature of the water was maintained at 25 ° C., and once every hour, 4.2 liters of water were set to automatically flush at a flow rate of 4.2 liters / min. The remaining rate was measured from the weight. The test condition 2 shown in FIG. 6B was the same as the test condition 1 except that the temperature of the inflow water of the low tank was maintained at 5 ° C. Test condition 3 shown in FIG. 7A was set so that the temperature of the inflow water in the low tank was maintained at 25 ° C., and 9.0 liters of water were automatically flushed at a flow rate of 4.5 liters / min. Other conditions were the same as the test condition 1. The test condition 4 shown in FIG. 7B was the same as the test condition 3 except that the temperature of the inflow water of the low tank was maintained at 5 ° C.

  The test condition 5 shown in FIG. 8 (a) is that the low tank of the household toilet (TOTO S670 manufactured by TOTO Kiki Co., Ltd. is a tank in which water does not directly come into contact with the drug supply device, but the main body of the drug supply device tends to be flooded. ), The temperature of the inflow water in the low tank is maintained at 25 ° C, and 3.3 liters of water is automatically flushed at a flow rate of 3.3 liters / min once an hour. The remaining rate was measured from the weight of the sample (drug 9). The test condition 6 shown in FIG. 8B was the same as the test condition 5 except that the temperature of the inflow water of the low tank was maintained at 5 ° C.

  The medicine 9 was prepared by kneading a fragrance, an anionic surfactant, a nonionic surfactant, an inorganic salt, and a dye, and molding the mixture into a truncated cone having a bottom diameter of 20 mm, a height of 23 mm, and a weight of 20 g.

  6 to 8, the vertical axis represents the remaining rate, and the horizontal axis represents the number of flashes. The test results are shown by bold lines in the examples and by dotted lines in the comparative examples. Test conditions 1 and 2 These are normal conditions of use. At 25 ° C., they are slightly elongated, but there is almost no difference from the conventional container. However, under the conditions that accelerate the dissolution of the drug 9 under the test conditions 3 to 6, the one that dissolves quickly in the conventional container is not much different from the normal state in the container of the present invention, and is stable. Dissolution can be allowed. 6 to 8, the residual amount ratio in the initial stage of the test tends to decrease after exceeding 100%, which is because the drug 9 swells due to the absorption of water and becomes heavy.

  In this way, even if the way of water flowing out of the water supply pipe of the water storage tank 1 differs depending on the flush toilet tank maker or model, it is possible to adjust the inflow and drainage of water into the medicine container 23, Since the contact between the water and the medicine 9 is appropriately regulated, the supply rate of the medicine 9 by dissolution in water can be always kept constant, and the collapse of the medicine 9 due to the water flow can be prevented. Therefore, it is possible to prevent the generation of the lumps of the disintegrated drug 9 and the solution dissolved more than necessary, and it is possible to always supply a stable solution to the flush toilet. For example, even when a lump or a high-concentration solution is generated, it can be directly discharged from the drain port 14 at the center to the water storage tank 1 without flowing out to the receiving tray 2 by the impermeable wall 11. The saucer 2 can be prevented from being colored or stained.

  Moreover, since the upper part of the water blocking wall 11 is open, the fragrance from the medicine 9 can be diffused. Thereby, not only the detergent but also the fragrance can be put in the medicine 9 itself. Therefore, since the number of the medicines 9 can be reduced to one, the manufacturing process is simplified and the cost can be reduced.

  In the above embodiment, the case where the impermeable wall 11 is formed integrally with the main body is illustrated, but the present invention is not limited to this, and various forms are adopted as shown in FIGS. 7 and 8. be able to. For example, FIG. 9A shows a configuration in which the main body and the cylindrical water-impervious wall 11 are formed by separate members and engaged by the engaging hand throw 21. The engaging hand throw 21 is formed by engaging an engaging hole formed in the outer periphery of the lower part of the cylindrical water-impervious wall with a claw projecting from the bottom of the main body. FIG. 9B shows a form in which a part of the bottom of the bowl of the main body is raised in a mountain shape to form a raised wall 24.

  FIGS. 10 (a) and 10 (b) show a case where cylindrical water-impervious walls 11 are protruded from the lid 7 and the main body 5, respectively. An example in which the diameter is formed larger than the water impermeable wall 11 on the main body 5 side is shown, and a gap 25 is formed between both the water impermeable walls 11 to allow the fragrance from the medicine 9 to diffuse to the volatilization opening 10 side. FIG. 10 (b) shows a water impervious wall 11 having the same diameter protruding from the lid 7 and the main body 5. The ends are formed short so that their ends do not contact each other. A gap 26 for diverting the gas toward the volatilization port 10 is formed.

  FIG. 11 shows a water-impeding hand, in which a water-impeding piece 22 is formed so as to cover the medicine container 23 side of the volatilization port 10 of the lid 7. The cantilever 10 protrudes outward in the radial direction from the edge of the lid 7 at the center side of the lid 7 in a cantilever manner. As a result, the water flowing from the volatilization opening 10 hits the water-blocking piece 22 and falls from the outer end side to the bottom of the main body, and almost never comes into contact with the medicine 9 stored in the storage section 23 in the center of the main body. Absent.

FIG. 12 shows a single drain port 24 which also serves as a volatilization port 10 and a surplus water discharge port 14a. FIG. In this example, the fragrance from the medicine 9 is diffused from the upper portion of the drain port 24, and the excess water is drained from the lower portion. In addition, the drain port 24 can be set in various shapes such as a slit shape and a plurality of round holes, but at least excess water such as water dropped from the volatile port 10 and excess water flowing from the intake port 13 is removed. Since it is discharged to the outside of the supply tool, it is preferably formed below the outer wall of the supply tool.

As described above, according to the present study, since the water impingement is provided to prevent the water flowing from the volatilization opening from entering the storage section, the water flowing from the volatilization opening directly contacts the medicine. Since the drug is dissolved only by the water flowing from the water intake port, a stable drug solution can always be supplied in an appropriate amount, and the effect of the drug can be exhibited in an assumed period. Further, since the number of medicines is one, the assembling work of the user can be simplified and the manufacturing cost can be suppressed.
